ployed in works of public utility. The tanks, wells, and canals for irrigation, without which in many tropical climates cultivation could hardly be carried on; the embankments which confine the rivers, the bazars for dealers, and the seraees for travellers, none of which could have been made by the scanty means in the possession of those using them, owe their existence to the liberality, and enlightened self-interest of the better order of princes, or to the benevolence or ostentation of here and there a rich individual, whose fortune, if traced to its source, is always found to have been drawn immediately or remotely from the public revenue, most frequently by a direct grant of a portion of it from the sovereign.
The ruler of a society of this description, after providing largely for his own support, and that of all persons in whom he feels an interest, and after maintaining as many soldiers as he thinks needful for his security or his state, has a disposable residue, which he is glad to exchange for articles of luxury suitable to his disposition: as have also the class of persons who have been enriched by his favour, or by handling the public revenues. A demand thus arises for elaborate and costly manufactured articles, adapted to a narrow but a wealthy market. This demand is often supplied almost exclusively by the merchants of more advanced communities, but often also raises up in the country itself a class of artificers, by whom certain fabrics are carried to as high excellence as can be given by patience, quickness of perception and observation, and manual dexterity, without any considerable knowledge of the properties of objects: such as some of the cotton fabrics of India. These artificers are fed by the surplus food which has been taken by the government and its agents as their share of the produce. So literally is this the case, that in some countries the workman, instead of taking his work home, and being paid for it after it is finished, proceeds with his tools to his customer's house, and is there subsisted until the work is complete.
